Automatically set results when status is given

[Drarig29]

If somebody does:

await manager.update.match({
  id: 1,
  status: Status.Completed,
  opponent1: {
    score: 12,
  },
  opponent2: {
    score: 14,
  },
});

Then the winner will be determined automatically, based on the scores. (only if the no result property is given)
